BURNER.

SPECIFICATION forming part f Letters Patent No. 613,649, dated November1, 1898. Application filed June 21, 1898. Serial No. 684,065. (Nomodel.)

ToaZZ whom it may concern:

Be it known that we, HARRY M. HAMRIK and WILLIAM S. MILLER, citizens ofthe United States, residing in the city and county of Philadelphia,State of Pennsylvania, have invented a new and useful Improvement inBurners, which improvement is fully set forth struction of burner forilluminating purposes;

and the object is to provide a burner of this character wherein thegasolene or other liquid illuminant will be converted into a gas orvapor after having left its source of supply prior to or at about thetime of its admission into the burner, means being provided forcontrolling the supply to said burner and for retaining a largeproportion of the heat within the burner in order that a superior gasmay be generated therein and a more perfect combustion thereof result.

It also consists of a suitably-supported mantle suspended above andadjacent to the mouth of the burner, whereby the llame as it emanatesfrom the burner and surrounds the mantle will be spread or deflected, soas to increase the illuminating power thereof, and whereby also the heatunits which are contained in said mantle may be returned to the burner,and thus intensify the heat thereof to a maximum degree.

It also consists of a burner comprising a shell or tube, agas-generating chamber lo cated at one end thereof, and a perforateddiaphragm located within said tube and intermediate of its ends, meansfor supplying said gas-generating chamber with gasolene or other liquidilluminant and for controlling the supply thereof to said burner, andmeans for retaining and intensifying to a maximum degree the heat insaid burner when in operation.

It further consists of novel details of conn struction, all as will behereinafter fully set forth, and particularly pointed out in the claims.

Figure l represents a side elevation of a burner embodying ourinvention. Fig. 2 represents a longitudinal section of the same,

showing also the preferred arrangement for supplying said burner withthe gasolene or other illuminant. Fig. 3 represents an inverted planview, on an enlarged scale, of a ring to which the mantle is secured andwhich forms a support therefor. Fig. 4 represents a longitudinal sectionof the mantle and its adjuncts. Fig. 5 represents a side elevation ofthe supporting-ring for the mantle in detached position. Fig. 6represents a longitudinal section of a slightly-modified con structionof our invention. Fig. 7 represents a side elevation of the same, theburner being shown in this instance as provided with an asbestos orother refractory cover.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates the burner, the same consistingof a shell or a tube B, having a series of perforations C near its lowerextremity for the admission of air and a series of perforations D nearits upper extremity through which a portion of the flame escapes whenthe burner is in operation.

E designates the threaded neck or extension of a casing F, to which thelower internally-threaded extremity of the shell or tube B is secured,the said casing being provided with a chamber Gr, the latter having aport 'H leading therefrom into the shell or tube B and through which thegas generated within the chamber Gescapes into the burner. The lower endof the casing is provided with a threaded opening adapted to receive thethreaded stem K of a needle or similar valve L, which serves to controlthe supply of gas to the burner, although it is evident that undercertain conditions we may dispense with said valve and reduce the sizeof the port Hin order that a predetermined and continuous supply ofilluminant may be introduced to the burner.

M designates a supply-pipe which may lead from any convenient source ofsupply, (not shown,) and the gasolene or other liquid illuminant may beforced or allowed to pass into the chamber G through said pipe, it beingobserved that the pipe M in Fig. l leads directly to the chamber G,while in Fig. 2 it is coiled around the burner A before entering saidchamber,the latter arrangement being IOO intended to heat the gasoleneto a higher degree as it passes through the coil and so facilitate andaccelerate the production of the gas.

The interior of the burner A is provided with a perforated or gauzediaphragm P, the same being located slightly below the level of theperforations D, so that as the gases rise within the shell B andcommingle with the air drawn in through the perforations C their ascentwill be retarded by said diaphragm and a perfect combustion at thatpoint will ensue, the flame being contained'within the said shell orcasin g between its upper extremity and the diaphragm will radiatethrough and heat the burner, and any flame which may pass out throughthe perforations D will give additional heat to the exterior of theburner, as will be evident.

Q designates a frame, the same consisting of an arm or standard T,having its lower extremity attached to a collar R, the latter beingformed with an annular top flange S, adapted to rest upon the upperextremity of the shell or casing B, the lower edge of said collarterminating above the perforations D.

The upper extremity of the arm Q is provided with a laterally-extendingsupport U, which may be arranged in substantial alinelnent with thecollar R and upon which pins V of a ring W rest, the latter beingsecured to and forming part of an inverted conical mantle A', the actionof which is similar to that of a VVelsbach mantle.

The ring YV is formed with an annular groove X and an adjacent flange'Y,having radial recesses Z, in which the ends of a plurality of strands ofwire are inserted, the same being secured therein by means of a wire Bor other suitable fastening, fitting into the groove X and binding theends of said strands, the lower to the converging ends of wires C,whereby a substantial and effective mantle is secured.

Referring now to Figs. 6 and 7, BX designates a shell or tube similar tothat hereinbefore described; but in this construction the lowerperforations C are omitted, and in their stead a space OX is leftbetween the lower extremity of the shell or tube and a casing FX for theadmission of air into the burner A, to which latter the supply-pipe MXis brazed or otherwise secured. The casin g FX is provided with a portor orifice GX, adapted to receive therein the lower extremity of thesupplypipe MX, which latter leads to the gas-generating chamber G, asshown, and in this manner a convenient and substan tial support isprovided for the valve-casing, as will be evident.

NXdesignates a cover or casing, which may be composed of asbestos orother refractory material, the same being provided with perforations PXat or near the lower extremity thereof for the admission of air to theburn er, the said cover being designed to inclose the burner in suchmanner that while serving to extremities thereof being fastened.

retain and intensify the heat therein it will 'in no wise interfere withthe free circulation of the air, which may pass up from below the coverand through the perforations PX therein, as described. This cover may beapplied to any of the forms of burners herein shown and described and isparticularly advantageous in winter time or under conditions where a lowtemperature prevails.

It will be understood, of course, that the valves for controlling thesupply of gasolene or other liquid illuminant to the burner and 'themantle and other parts or adj uncts specifically described as pertainingto Figs. l to 5, inclusive, and not referred to in connection with Figs.6 and 7 will be used therewith in substantially the same form.

It has been found in practice that-the best results are obtained bymaking the ring WV oi' copper, as well as the support U, the standard Q,and the collar R, the mantle A being preferably made of platinum orsimilar inaterial.
